EDWARD F. PITTMAN, OF KEOSAUQUA, IOW'A.

COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 716,577, dated December 23, 1902.

Application filed October 6, 1902.

T0 1f/ZZ wiz/0m, it may con/cern:

Be it known that I, EDWARD F. PITTMAN, a citizen of the United States, residing at Keosauqua, in the county of Van Buren and State of Iowa, have invented a new and useful Copy-Holder, of which the following is a specification.

This invention relates generally to copyholders, and particularly to structures of that class adapted for use interchangeably in connection either as a desk appurtenance or an attachment to a book type-writer.

The holder of the present invention is designed as an improvement upon a copy-holder for which Letters Patent of the United States were granted to me December l0, 1901, No. 688,332.

The novelty of the present invention resides in details of improvements in certain parts, particularly in the construction and manner of mounting the feed-roller and upper and lower presser-rollers, in the manner of associating the copy-guide with the shaft of the lower presser-roller, in the means for holding the two presser-rollers in engagement with the feed-roller, in the mechanism for throwing the presser-rollers out of engagement with the feed-roller, and in the general manner of arrangement of the parts of the device.

The invention further resides in an improved means for attaching the device to a book type-writer in such manner that it will travel with the carriage, thus to be constantly opposite the operator.

In the copy-holderconstituting the subjectmatter of the patent to which reference has been made the feed and presser rollers are of a length equal to a sheet of legal-cap or typewriter paper. In practice it is found that this width of the rollers is objectionable in some instances-for example, in copying from sheets of paper bound together by staples or eyelets disposed at the ends and intermediate of the ends thereof, which prevent ready feeding of the paper between the rollers. As a matter of specific improvement in the present invention the operative surfaces ot' the feed-roller are of a width approximately that of the written line of an ordinary sheet of legal-cap paper, and a length of the center portion of said roller is removed, or, in other Serial No.126,131. (No model!! words, the roller is reduced in transverse diameter to leave a gap or space through which intermediate fasteners may pass. The presserrollers are divided, and the two sections of each are of a width equal to the operative surfaces or end portions of the feed-roller, so that in the use of the machine any fastening devices that may be associated with the paper being copied will in no wise interfere with the proper operation of the said rollers.v

The invention further contemplates the employment of a paper support to be attached to the rear of the copy-guide to effect counterbalancing thereof, thus to cause its front edge always to lie against the sheet of paper being copied, the said support also subserving the function of a defiector' to prevent the paper from coming in contact with the operative parts of the type-writer when the structure is employed on a book typewriter.

With the above-stated and other objects in view the invention consists in the novel construction and combination of parts of a copyholder, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specilication, and in which like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carryingthe same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, Vand exact manner of assemblage without departing from the spirit thereof, and in these drawings- Figure l is a view in elevation taken from the front of the structure. Fig. 2 is a view in vertical transverse section taken on the line 2 2 of Fig. l. Fig. 3 is a similar view taken on the line 3 3 of Fig. l and looking in the direction of the arrow thereon. Fig. 4t is a perspective detail view of an attachment to be secured to a book type-writer by means of which the copy-holder may be detachably associated with a type-writer. Fig. 5 is a perspective detail view of a paper-support to be attached to the copy-guide. Fig. 6 is a detail perspective view showing one terminal loop of a spring employed for holding the presser-rollers against the feed-roller.

IOO

The supporting-frame of the copy-holder is, by preference, constructed of a single piece of sheet metal and comprises a base-plate 1 and end standards 2. The base-plate has secured to it by screws 3 a base proper, 4, constructed of wood and having its under face covered by felt 5, as shown in Fig. 3. This felt is employed when the machine is to be used on a table or type-writer desk to obviate noise and any marring of such articles of furniture; but where the structure is employed in connection with a book type-writer machine the felt may be omitted. The upper face of the base 4 at a point midway of its ends is provided with a transverse recess 6 to be engaged by a clamping device 7 to be permanently attached to the carriage of a book type-writer machine. This clamp is approximately U-shaped in cross-section and is constructed of spring metal, and its lower member is provided with two legs 8 at its front and toward its rear with a centrally-disposed leg 9, these legs being disposed downward lwhen the device is associated with the machine and are designed to embrace the front portion of the machine-carriage and to be held in position thereon by screws passed through openings 10 in the lower member. The upper member 11 is designed to engage the recess 6 in the base proper, as shown in Fig. 2, and the lower member to bear against the under side of said base and by frictional contact therewith to hold the copy-holder in position.

Mounted in bearings formed in the end standards 2 is a shaft l2, upon which is mounted the feed-roller 13, the same, by preference, being constructed of wood or wood fiber and is held from turning independently of the shaft by end plates 14, secured thereto by screws 15, one of the plates being rigidly secured to the shaft by a screw 16. The intermediate portion of the roller is cut away at 17 to present a gap or space through which paper-fastenings oreyelets employed forholding sheets of paper together will pass when the roller is turned, thus to obviate any interference with its proper operation. The enlarged terminals of the roller and which constitute the paper-feed elements are peripherally covered by a rubber facing 18, as clearly shown in Fig. 1.

The terminals of the shaft 12 exteriorly of the standards 2 are provided with knobs 19, by which the roller may be turned, as is usual with devices of this character.

Mounted in slotted bearings 2O in the standard and arranged in vertical alinement are two shafts 2l and 22, upon each of which are mounted two presser-rollers 23 23 and 24 24, each of the upper pair of rollers 24 being of a length equal to the enlarged terminal portions of the feed-roller and each of the lower pair 23 being of less length than the said terminal portions, as clearly shown in Fig. 1. These rollers are, by preference, constructed of a wood 0r other suitable core covered by a rubber facing 25. The rollers are loosely mounted on the shaft and are heldin proper operative relation with the feed-roller and against longitudinal movement on their shafts by sleeves 26, 27, and 28 for the shaft 21 and similar sleeves 29, 30, and 31 for the shaft 22.

The intermediate sleeves 27 and 30, respec-A tively, of the two shafts are loose thereon; but the terminal sleeves 26 28 29 31 of the respective shafts are held from turning on their shafts and the shafts themselves from rotation by rectangular loops 32 and 33 of coiled springs 34, which springs operate to hold the presser-rollers normally in contact with the feed-roller. The lock of the shafts 21 and 22 and the terminal sleeves thereof is effected by providing a transverse slot 36 in each of the sleeves and a transverse recess 37 in each terminal of the shafts, and the crests of the loops are passed through the slots and into the recesses of the shafts, as clearly shown in Fig. 1, thus accomplishing the purpose designed. To facilitate disconnection of the springs from the shafts when desired, the free end of each loop is provided with a toe 38, which is passed through the upper whirl of each end of the spring, as shown in Fig. 6.

As a means for moving the presser-rollers out of engagement with the feed-roller when it is desired to insert a number of sheets of paper between the said rollers two releasingplates 39 are employed, which are loosely mounted upon the shaft 12 and have their ends disposed at an angle to their length, as shown at 40, thus to present cam-surfaces to impinge the inner surfaces of the terminal collars of the shafts 21 and 22. The releasingplates are held against longitudinal movement upon the shaft by collars 41 42, as clearly shown in Fig. 1. The releasing-plates are connected by a releasing-rod 43, riveted to the plates and which on being rocked will bring the releasing-plates into engagement with the shafts 21 and 22, and thus force them away from the feed-roller.

The copy-guide 44 is approximately semicircular in cross-section and provided on its under side with two downturned ears 45, having orifices through which the shaft 22 passes, thus to effect a pivotal connection between the parts, the said guide being held against longitudinal movement upon the shaft by the sleeve 30. Adjacent to each ear the copyguide is provided with a longitudinal opening 46, through which the presser-rollers 23 project, thus to contact with the feed-roller, as clearly shown in Fig. 1. The rear side of the copy-guide is curved slightly downward and outward, as at 47, and has detachably associated with ita paper-support 48, (shown in detail in Fig. 5,) which operates not only to prevent the paper from dragging upon the operative parts of the machine when the structure is employed in connection with the type-writer, butl also serves to counterweight the rear portion of the copy-guide, thus to cause its front portion to lie closely against the sheet being IOO IIO

copied. This feature is one of importance, inasmuch as it obviates the necessity of employing a spring or springs for the purpose and will allow the copy-guide without resistance to rock as the paper is fed through the apparatus.

To hold the standards 2 properly spaced apart and also to impart the requisite rigidity to the device, a tie-rod 49 is employed, the terminals of which pass through suitable orices in the upper ends of the standards and are clamped thereto by nuts 50.

By the details of construction herein defined the copy-holder is rendered thoroughly efficient in use and is free from objections inherent to devices of this character commonly in use.

All of the parts may be cheaply and readily manufactured and may be madein standard sizes, so that in the event of damage or breakage to a part or parts repairs may be readily and cheaply effected.

Having thus described the invention, what I claim isl. A copy-holder having a feed-roller provided with enlarged terminal portions constituting paper-feeding elements, the intermediate portion of the roller being reduced in diameter.
